Add external PLATFORM access on arm, and use it in the pl310 driver.

This allows multiple instances of SoCs that use the pl310 driver to be
built within the same kernel:

* Add access to the platform_t object from outside platform.c
* Use this with the pl310 driver

There is a new platform_pl310 interface to replace the existing code. SoCs
need to implement the init method, and if they have special requirements to
write to the two registers we care about will also need to implement the
write_ctrl and write_debug methods.

Remove the MULTIDELAY option from arm. It's now enabled when PLATFORM is
enabled.

Remove PLATFORM_SMP. It's unneeded as all configs with both PLATFORM and
SMP use it so we can switch to the combination of these as the check.

Allwinner: Add support for H2 Plus SoC

H2+ SoC is a stripped down version of H3 without gigabit ethernet and 4K HDMI.
Also add sun8i-h2-plus-orangepi-zero.dts to the build as we run on this board.

Remake support for SMP kernel on UP cpu:
- Use new option SMP_ON_UP instead of (mis)using specific CPU type.
By this, any SMP kernel can be compiled with SMP_ON_UP support.
- Enable runtime detection of CPU multiprocessor extensions only
if SMP_ON_UP option is used. In other cases (pure SMP or UP),
statically compile only required variant.
- Don't leak multiprocessor instructions to UP kernel.
- Correctly handle data cache write back to point of unification.
DCCMVAU is supported on all armv7 cpus.
- For SMP_ON_UP kernels, detect proper TTB flags on runtime.
